Energy saving control
z
Human sensor catches movements of people in a room, and operates with lower capacity when the room
is empty. When people come back to the room, it automatically returns to previous operating mode.

10°C HEAT Operation
z *Only available with Wireless RC.
The room temperature can be set to go no lower than 10°C,
thus ensuring that the room does not get too cold when not occupied
Caution)
When the room temperature is higher than 10°C, “•10°C HEAT” operation does not start. Operation starts and maintains the room
temperature at 10°C when the temperature drops below 10°C.
When “•10°C HEAT” operation stops, the room set temperature quickly returns to the preset temperature.
Outdoor unit low noise
z *Only available with Wireless RC.
When air-conditioner operates in large capacity, operation noise of outdoor unit will be suppressed. In case
of room temperature being close to setting temperature, operation noise might not decrease.
